SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 593,781, dated November16, 1897.

I Application filed February 14, 1893. Serial No. 462,294. (No model.)

To all whmn it may concern.-

Be it known that I, ADDISON Fos'rnn PURE- FOY, acitizen of the UnitedStates, residing at WVake Forest, in the county of Wake and State ofNorth Carolina, have invented certain new and useful Improvements inSpring Bed-Bottoms; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

' This invention relates more particularly to the meansfor connectingbrace-wires and coiled wire springs together in bed-bottoms andanalogous structures, as chair-seats and the like.

' In the accompanying drawings, Figure I is a partial plan'of a springbed-bottom constructed in accordance'with the invention. Fig. II is apartial section on line 'i i of Fig. I.

In the drawings the structure at one corner only of a spring bed-bottomis represented. The parts omitted may be duplicates of those shown. Itis intended to employ hour-glass springs and to have a like arrangementof brace-wires on each end of the same; but any ordinary or suitableform of springs may be used, secured to any appropriate base. As shown,the springs A, which make up the body of the bed-bottom, are connectedwith one another by the brace-wires B, running lengthwise'and widthwiseof the bed-bottom. The wires B are connected with the springs by meansof couplings O and 0, having loops 1 at each end and an oblique middleportion 2 and formed of a wire bent into the general form, in plan, ofthe figure 8. The bracewires 13 running lengthwise are shown asseparately secured to each of the spring-wires which they intersect bymeans of an appropriate coupling. Each coupling extends around thespring-wire and has its ends engaged by the cross-wire which is threadedthrough the loops at the ends thereof.

In order to apply the coupling in the most firm manner, the brace-wirewhich passes through the loops or openings is bent about the wire orwires (whether one or more springwires or brace-wires, or both) whichthe middle portion of the coupling ineloses, so that there is lessliability for the brace-wire to pull through.

In applying the coupling the same is bent sufficiently for the loops oropenings at the ends to receive the brace-wire while the latter isstraight, and then the coupling and crossed wires are compressed,thereby bending the brace-wire outward around the spring-wire andforcing inward the ends of the coupling to make a smooth surface. Thespring-wire is confined between the middle portion 2 of the coupling andthe brace-wire B. By having a separate coupling for each intersection ofthe brace and spring wires the springs may be set any desired distanceapart. It is possible, however, and where the springs are set closelytogether advantageous, to use one coupling to attach two adjacentsprings to each other and to a brace-wire intersecting both. Theadvantage in this arrangement is in lessening the number of joints inthe bedbottom and also the number of couplings. Although it could beapplied to other brace- 'wires,-it is shown only in connection with thebrace-wires running widthwise of the bedbottom, the couplings 0 beingbent around the wires of adjacent springs A and having the brace-wiresinserted in the loops or openings 1 of the couplings and bent outwardaround the inclosed spring-wires.

At the ends each brace-wire B is bent into a loop 3, and the end 13* ofeach brace being lapped upon the body portion of the same brace-wire issecured thereto by means of a coupling (3*, similar or identical withthe couplings O C. The border-wireD is secured to the edges of the topcoils of springs A by means of the looped ends 3 of the brace-wires andhas each of its ends-D* twisted about the spring-wire of the end springand secured thereto by an eye 4. The brace-wires are preferably fiat.The spring-wires, the wires of the couplings, and the border-wires arepreferably round. v

I claim as my invention or discovery 1. A brace-wire having at the end aloop formed by lapping said wire upon itself, in

combination with awire threaded through i said loop, and a couplinghaving openings at the ends with the lapped portions of the bracethreaded through said openings and bound together by said coupling,substantially as described.

2. In combination with the coiled wire IOO springs of a bed-bottom,brace-Wires having the ends looped about spring-wires and being securedalso to the spring-Wires where they cross the same, the lapped ends ofthe braces being secured to the body portions thereof by bent-Wirecouplings having a loop at each end which receives the lapped portionsof the brace-Wires and an oblique body portion which crosses andconfines them, and similar couplings securing the brace-wires to thespring- 10 wires at their crossings, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
